"I met Suri. She is really beautiful. She is really special," the 32-year-old actress told reporters Thursday at the London premiere of her new film, Volver. "One of the most beautiful babies I have ever seen. And I am extremely happy for them. They are really happy and doing great."

Cruz, who dated Cruise from 2001 to 2004, declined to offer other details of the meeting.

Suri, the daughter of Cruise, 44, and Katie Holmes, 27, hasn't been seen in public since she was born on April 18.

But this month, Jada Pinkett Smith told PEOPLE that she also has seen the baby. "She's one of the sweetest babies I've ever met in my life," she said. "She's an absolute beauty and she's Daddy's little girl."

Cruise's pal and fellow Scientologist, Leah Remini, has also met Suri. The King of Queens star told PEOPLE Suri "looks like Tom and Katie. She's just beautiful."

In other Cruz news, when asked at the London premiere about another ex-boyfriend, Matthew McConaughey, with whom she split in June, her eyes became teary. "I'm not going to talk about it," she told PEOPLE. Reporting by KARLA ADAM
